TYPE-WRETING MAGHINE.

' Patented April 16, 1907.

To all whom it may concern:

Be it ,known that I, HARRY S. MCCOR- MACK, a citizen of the UnitedStates, residing in New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Type-WritingMachines, of which the following is a specification. This inventionrelates to the paper-carry ing devices of type-writing machines, andparticularly to those in which it is desired to retain one sheet in themachine while another sheet is removed and a third one introduced.

Usually the retained sheet is intended to re ceive a carbon record ofall the entries made The record-sheet'is usually very long, while theothers are short. The long record-sheet usually hangs over the back ofthe machine, together with the usual long carbon-sheet, and are found tobe in the way during the introduction of the small per-shelf 6,inclining upwardly and rear sheets at the rear of the machine. In orderto overcome this difiiculty, I provide a device for throwing the longsheets forwardly over the top of the platen, thus leaving the rear ofthe machine clear for the convenient introduction of the next shortsheet. Said device is in the form of a flap, and preferably is just infront of the usual rear paper-shell, whereby the flap serves also as ashelf for supporting the long sheets. The flap is preferably in the formof a light zigzag wire frame, but heavy enough to hold down the sheetsover the platen.

in the accompanying drawings, Figure 1 is a front elevation, partly insection, of the platen and platen-frame of an Underwooc front-strikewriting-machine with my in provenients applied thereto. Fig. 2 is asectional elevation of the same, showing the long record-sheet and shortbill-sheet in posi tion for writing. Fig. 3" shows the long record-sheetthrown forwardly and held down out of the way by the flap during theintroduction'of another short bill-sheet. Fig. 4 is a plan illustratingone joint of the flap-hinge;

Types 1 strike rearwardly upon the front side of a, platen 2, having anaxle 3, whereby it is mounted in the ends 4 5 of a platen frame-thelatter also including the usual pawardlyironi the platen-and at itsforward portion curving around under the platen, as

- usual. Releasable rolls 7 press against the under side of the platen,and front paperguides 8 slide along a rod 9, as usual, so that the paperis guided and fed around the platen in the usual manner.

The long record-sheet 10 is passed around the platen, Fig. 2, and restsupon a flap 11 in the form of a wire frame, the wire being bent endportions in a pair of cars 12, projecting up from the platen-frame ends.are just in front of the paper-shelf 6, and the frame 11 extendsupwardly and rearwardly from its hinge-joints and is provided outside ofsaid ears with short arms 13, which rest'at 14 upon the rear edges ofhorizontal portions 12 of the ears, said edges forming stops to preventthe flap from falling back farther. A short or bill sheet 15, Fig. 2, isseen passed around-the platen in position to be written carbon is placedbetween said sheets 10 and 15.

When the bill 15 is-completed', the'pres sure rolls 7 are released andthe bill withdrawn. Then usually the platen is turned back to receive anew sheet. At; this juncture the flap 11 is swungforward'and down, Fig.3, thereby throwing forward the sheet chine, the weight of the flapholding said duction of a fresh bill-sheet 15 at therear of the platen,said sheet passing in between the l paper-shelf and the flap. After thesheet 15 18 introduced the pressure-roll 7 is brought into action tohold the sheets, and the flap 11 is thrown back. to the Fig. 2 position,together as before. light, but at the same time of sufficient weight tobeheld by gravity in both positions at Figs. 2 and 3. v

I Variations maybe resorted to within the scope of myinyention.

Having thus described my invention, I claim.

' i. In a type-Writing machine having a platen and papenfeeding devices,the combination with a main p'aper-shelfin rear of the platen, of anauxiliary paper-shelf in the form oi a flap between the pa air-shelf andplaten and entending upwardly and rearwardly movable forwardly anddownwardly to hold long record-sheets down out of the Way,

while another sheet is introduced in rear of tute at all pointsanuninterrupted support upon, and it will be understood that the usualwith the sheet 18, and the writing proceeds The frame may be made very-ITO 2. ln'a type-wnting machine having a platen and means for feedingsheets around the same, the combination of a'main paperdown over theplaten; said flap normally extending u wardly and rearwardly from thetop of sai main pa er-shelf, and constructed to constitute at al pointsan uninterrupted support for the sheets.
